Simply put, Helix is a replacement for rebar. The unique, twisted design of Helix allows for efficient tensile stress re-distribution within the concrete prior to concrete cracking. The result is a significant increase in the concrete’s strain capacity and pre-crack properties. Unlike rebar and other forms of reinforcement, Helix provides proactive reinforcement which engages the concrete before large cracks form.
